A booster for a trailer system is provided comprising a control system in communication with a sensor(s) for determining the direction and speed of the booster when in motion. The control system comprises instructions corresponding to one or more booster operations such as: detection of a reverse state, retraction of a suspension system when the reverse state is detected; engagement of a steer axle lock when the reverse state is detected; detection of a forward state; extension of the suspension system when the forward state is detected; disengagement of the steer axle lock when the forward state is detected; detection of a high-speed forward state; engagement of the steer axle lock when the high-speed forward state is detected; detection of a low-speed forward state; and disengagement of the steer axle lock when the low-speed forward state is detected.

A flatbed, step-deck, double-drop deck, or lowboy trailer assembly comprises a plurality of metal crossmembers extending in a transverse direction of the trailer assembly; a metal deck supported by the plurality of crossmembers, the metal deck having an upper deck surface and a lower deck surface; and a pair of parallel wooden boards extending in a longitudinal direction of the trailer assembly proximate respective laterally opposite sides of the trailer assembly. Each wooden board in the pair of wooden boards is located in a respective recessed portion of the metal deck. The lower deck surface is situated between and separates a lower surface of each wooden board from the plurality of metal cross members. The lower deck surface is welded to the plurality of crossmembers.

The hybrid tractor truck can have a cabin supported by a frame, the frame including two transversally spaced apart beams extending behind the cabin, a fifth wheel supported by the frame behind the cabin, a front axle bearing front wheels, at least one rear axle supported by the frame behind the cabin, the at least one rear axle bearing rear wheels, a heat engine located in an engine compartment supported by the frame in front of the cabin, the heat engine drivingly connected to said at least one rear axle; and an electric machine supported by the frame behind the at least one rear axle, the electric machine being drivingly connected to the at least one rear axle, and at least one battery electrically connected to the electric machine.

A tank trailer configured to lower an overall center of gravity. The trailer includes a tank, a wheel assembly, an upper body height and a trailer length. The tank includes a cavity contained within a lower body, an upper body, a transitioning body, a front end and a rear end when the cavity within the trailer is filled with a liquid fluid, the liquid fluid is evenly distributed along the trailer length of the trailer since a diameter of the lower body, the upper body and the transitioning body are equal. Other trailers are presented.

Sleeper cabs for a gooseneck trailer. The gooseneck trailer includes a horizontal neck portion coupled to a cargo bed of a truck. The sleeper cabs include a base and an enclosure. The base is configured to securely mount to the horizontal neck portion of the gooseneck trailer. The enclosure defines a mobile dwelling supported on the base. In some examples, the sleeper cabs include a ladder to assist with climbing up to or descending from the enclosure.

A trailer adapted to haul one or more reels for carrying conveyor belts is disclosed. The trailer includes a loading means to lift the reel on the deck of the trailer. The loading means includes two articulated arms located each side of the trailer, each articulated arm comprising a first elongate member and a second elongate member pivotally mounted to the first elongate member. The first elongate members are movable relative to the trailer between a retracted position and a rearwardly extended position. The second elongate members are pivotable between a horizontal position and an upright position wherein the second elongate members are orthogonal to the first elongate members. A hoist is disposed between the second elongate members and is operable to lift the reel from the support surface to an effective height greater than an effective height of the deck. Jacks are also provided to stabilise the loading means.

A powered side panel system is used in conjunction with a loading bed found on trailers and other flatbed vehicles. The system includes a side panel having a vertical member. The side panel is configured to pivot about a panel axis in communication with the trailer. A lever arm extends between the side panel and the trailer. The system includes a reciprocating assembly to operate the lever arm between a lowered and raised orientation. The reciprocating assembly communicates with the lever arm through a cable. The lever arm controls the rate of radial motion of the side panel about the panel axis. A control unit is configured to regulate the operation of the actuator device.

A semi-trailer for transporting a load to be moved has a wheeled front module having a right-hand front row and a left-hand front row of front bogies each provided with a respective hydraulic suspension driven by its own hydraulic cylinder; a wheeled rear module comprising a right-hand rear row and a left-hand rear row of rear bogies each provided with a respective hydraulic suspension driven by its own hydraulic cylinder; a coupling unit of the wheeled front module for the coupling to a tractor and comprising a pair of hydraulic jacks for transferring a part of the load to be moved to the tractor; a first hydraulic unit interposed between the hydraulic cylinders of the front and rear rows of bogies and configured in such a way that the sum of the instantaneous load-supporting pressures acting on the hydraulic cylinders of the right front row and of the cylinders of the left-hand rear row is equal to the sum of the instantaneous pressures controlling the cylinders of the left-hand front row and of the cylinders of the right rear row; and a second hydraulic unit configured to control the hydraulic jacks based on the sum of the instantaneous load-supporting pressures acting on the hydraulic cylinders of said right front row and of said left-hand front row.

A container chassis with detachable bolster ends comprising a plurality of bolsters, each bolster with detachable bolster ends and a first configuration with detached bolster ends wherein the container chassis is less than eight feet in width for horizontal fitment into an ISO shipping container. The container chassis with detachable bolster ends may also be configured to stack vertically within a plurality of container chassis and wheeled into the ISO shipping container.
